Background: Hip dislocation is a rare occurrence during sports but carries serious implications for athletes. Purpose: To systematically review treatment strategies and outcomes for hip dislocation in athletes, with the ultimate goal of providing sports medicine physicians with the information necessary to appropriately treat and counsel patients sustaining this injury. Study Design: Systematic review; Level of evidence, 4. Methods: PubMed, MEDLINE, and Embase were searched for studies relating to hip instability and athletics from January 1, 1989 to October 1, 2019. Abstracts and articles were evaluated on the basis of predefined inclusion and exclusion criteria. Inclusion criteria were the following: (1) data from ≥1 patients, (2) native hip dislocation or subluxation occurring during sports, (3) patients aged at least 10 years, and (4) written in English. Exclusion criteria were (1) patients younger than 10 years; (2) nonnative or postoperative hip dislocation or subluxation; (3) a native hip injury without dislocation or subluxation; (4) patients with dislocation or subluxation secondary to neuromuscular, developmental, or syndromic causes; (5) dislocation or subluxation not occurring during sports; (6) patients with physeal fractures; or (7) review articles or meta-analyses. Data were recorded on patient demographics, injury mechanism, treatment strategies, and clinical and radiographic outcomes. Where possible, pooled analysis was performed. Studies were grouped based on reported outcomes. Meta-analysis was then performed on these pooled subsets. Results: A total of 602 articles were initially identified, and after screening by 2 reviewers, 27 articles reporting on 145 patients were included in the final review. There were 2 studies that identified morphological differences between patients with posterior dislocation and controls, including decreased acetabular anteversion ( P = .015 and .068, respectively), increased prevalence of a cam deformity ( P < .0035), higher alpha angles ( P≤ .0213), and decreased posterior acetabular coverage ( P < .001). No differences were identified for the lateral center edge angle or Tonnis angle. Protected postreduction weightbearing was most commonly prescribed for 2 to 6 weeks, with 65% of reporting authors recommending touchdown, toe-touch, or crutch-assisted weightbearing. Recurrence was reported in 3% of cases. Overall, 4 studies reported on findings at hip arthroscopic surgery, including a 100% incidence of labral tears (n = 27; 4 studies), 92% incidence of chondral injuries, 20% incidence of capsular tears, and 84% incidence of ligamentum teres tears (n = 25; 2 studies). At final follow-up, 86% of patients reported no pain (n = 14; 12 studies), 87% reported a successful return to play (n = 39; 10 studies), and 11% had radiographic evidence of osteonecrosis (n = 38; 10 studies). Conclusion: Various treatment strategies have been described in the literature, and multiple methods have yielded promising clinical and radiographic outcomes in patients with native hip dislocation sustained during sporting activity. Data support nonoperative treatment with protected weightbearing for hips with concentric reduction and without significant fractures and an operative intervention to obtain concentric reduction if unachievable by closed means alone. Imaging for osteonecrosis is recommended, with evidence suggesting 4- to 6-week magnetic resonance imaging and follow-up at 3 months for those with suspicious findings in the femoral head.

Abstract Background Revision surgery after the Latarjet procedure is a rare and challenging surgical problem, and various bony or capsular procedures have been proposed. This systematic review examines clinical and radiographic outcomes of different procedures for treating persistent pain or recurrent instability after a Latarjet procedure. Methods A systematic review of the literature was performed using the Medline, Cochrane, EMBASE, Google Scholar and Ovid databases with the combined keywords “failed”, “failure”, “revision”, “Latarjet”, “shoulder stabilization” and “shoulder instability” to identify articles published in English that deal with failed Latarjet procedures. Results A total of 11 studies (five retrospective and six case series investigations), all published between 2008 and 2020, fulfilled our inclusion criteria. For the study, 253 patients (254 shoulders, 79.8% male) with a mean age of 29.6 years (range: 16–54 years) were reviewed at an average follow-up of 51.5 months (range: 24–208 months). Conclusions Eden–Hybinette and arthroscopic capsuloplasty are the most popular and safe procedures to treat recurrent instability after a failed Latarjet procedure, and yield reasonable clinical outcomes. A bone graft procedure and capsuloplasty were proposed but there was no clear consensus on their efficacy and indication.

Background: Femoroacetabular impingement (FAI) is a common pathology in athletes that often requires operative management in the form of hip arthroscopy. Purpose: To systematically review the rates and level of return to play (RTP) and the criteria used for RTP after hip arthroscopy for FAI in athletes. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of the literature, based on the PRISMA guidelines, was performed using PubMed, Embase, and Scopus databases. Studies reporting outcomes after the use of hip arthroscopy for FAI were included. Outcomes analyzed were RTP rate, RTP level, and criteria used for RTP. Statistical analysis was performed using SPSS software. Results: Our review found 130 studies, which included 14,069 patients (14,517 hips) and had a mean methodological quality of evidence (MQOE) of 40.4 (range, 5-67). The majority of patients were female (53.7%), the mean patient age was 30.4 years (range, 15-47 years), and the mean follow-up was 29.7 months (range, 6-75 months). A total of 81 studies reported RTP rates, with an overall RTP rate of 85.4% over a mean period of 6.6 months. Additionally, 49 studies reported the rate of RTP at preinjury level as 72.6%. Specific RTP criteria were reported in 97 studies (77.2%), with time being the most commonly reported item, which was reported in 80 studies (69.2%). A total of 45 studies (57.9%) advised RTP at 3 to 6 months after hip arthroscopy. Conclusion: The overall rate of reported RTP was high after hip arthroscopy for FAI. However, more than one-fourth of athletes who returned to sports did not return at their preinjury level. Development of validated rehabilitation criteria for safe return to sports after hip arthroscopy for FAI could potentially improve clinical outcomes while also increasing rates of RTP at preinjury levels.

Abstract Background: Playing tennis is associated with various movements that can lead to labral injuries and may require arthroscopic surgery. While hip arthroscopies have demonstrated good outcomes in athletes, there is limited literature reporting Patient Reported Outcomes (PROs) and return to play in competitive or recreational tennis players after hip arthroscopic surgery. Therefore, the purpose of the present study was to (1) report minimum five-year PROs and return to sport in tennis players who underwent hip arthroscopic surgery and (2) compare outcomes between recreational and competitive tennis players.Methods: Data for patients who underwent hip arthroscopy surgery in the setting of femoroacetabular impingement (FAI) and labral tears between March 2009 and January 2014 and who played tennis at any level within one-year of surgery were retrospectively reviewed. Patients with preoperative and minimum five-year postoperative scores for the following PROs were included: modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sport Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain. Patients with preoperative Tönnis osteoarthritis Grade >1, Workers’ Compensation claims, age > 60 years old, or previous ipsilateral hip surgeries or conditions were excluded. Patient Acceptable Symptomatic State (PASS) and Minimal Clinically Important Difference (MCID) for mHHS and HOS-SSS were calculated. Results: Of 28 patients, 31 hips met all inclusion and exclusion criteria of which 28 (90.3%) had minimum 5-year follow-up (mean: 72.8 ± 13.9 months). There were 3 professional, 3 collegiate, 2 high school, 2 organized amateur, and 18 recreational level tennis players. All PROs significantly improved at latest follow-up: mHHS from 67.0 to 86.7 (P < 0.001), NAHS from 65.9 to 87.2 (P < 0.001), HOS-SSS from 50.0 to 77.9 (P = 0.009), and VAS from 5.4 to 1.8 (P < 0.001). There was a 75.0% return to sport rate. Additionally, 66.7% of patients achieved MCID and 83.3% achieved PASS for mHHS, and 63.6% achieved MCID and 58.3% achieved PASS for HOS-SSS.Conclusion: Regardless of the level of participation, tennis players who underwent hip arthroscopic surgery reported statistically significant PRO improvements. A favorable rate of return to sport was also achieved by players with a continued interest in playing. The severity of cartilage damage was shown to not influence rate of returned to sport nor PROs in this population. The data here may be useful in counseling tennis players of various levels who are considering arthroscopic treatment of a hip injury. Level of Evidence: IV

Background: There has been a recent increase in the use of biologics in hip arthroscopy to assist in the management of femoroacetabular impingement (FAI). Purpose: To analyze the current use of biologics for the treatment of FAI and its associated lesions. Study Design: Systematic review; Level of evidence, 4. Methods: A search of the PubMed, Medline, and EMBASE databases was performed in March 2019 with use of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The criterion for inclusion was observational, published research articles studying the therapeutic use of biologics as an adjuvant therapy during arthroscopic surgery for FAI; treatments included bone marrow aspirate concentrate, mesenchymal stem cells (MSCs), platelet-rich plasma (PRP), hyaluronic acid, growth factors, and autologous chondrocyte implantation (ACI) or autologous matrix-induced chondrogenesis (AMIC). Results: There were 9 studies that met the inclusion criteria, and a total of 674 patients were included across all studies. FAI was studied in all articles. Further, 7 studies (78%) also analyzed chondral injuries, and 3 studies also analyzed labral tears (33%). ACI or AMIC was used in 56% of studies and showed superior functional outcomes at short- and midterm follow-up versus debridement or microfracture. PRP did not improve the outcome of labral repairs at short-term follow-up. Conclusion: The current literature regarding biologic adjuncts in hip arthroscopy is varied in quality, with only one level 1 study. The use of ACI/AMIC for medium-sized chondral lesions showed promising results in individual studies; however, these were of lower quality. To enable comparisons among future studies, investigators must ensure accuracy in the reporting of biologic preparations and formulations used and homogeneity in the type and severity of lesion treated.

ImportanceTears of the ulnar collateral ligament (UCL) of the elbow occur predominantly as an overuse injury, most commonly affecting throwing athletes, particularly baseball players. UCL reconstruction (UCLR) has been described as an effective treatment modality in the short term.ObjectiveThe purpose of this study was to systematically review the evidence in the literature to ascertain the clinical outcomes, complication and revision rates in baseball players following UCLR of the elbow at a minimum of 48 months of follow-up.Evidence reviewTwo independent reviewers performed a search of the literature based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the EMBASE, PubMed and Scopus databases. Clinical studies were included if they reported outcomes of baseball players at a minimum of 48 months following UCLR.FindingsOur review included 8 studies including 1104 baseball players (1105 elbows) at mean 69.9 months (48–205) following UCLR. The majority of baseball players were pitchers (92.3%), with a mean age of 22.2 years (13–42). At final follow-up, the overall return to play (RTP) was 95.3%%, with 85.3% returning at pre-injury level. In addition, the mean reported Conway-Jobe score was 86.8%, the revision rate was 6.0% with postoperative neuropathy reported in 2.4% of patients. A total of 479 (43.4%) were professional baseball players, with an overall RTP rate of 97.5% and 82.3% managing to RTP at their pre-injury level. The mean number of career years following UCLR was 4.7 years (0–22).Conclusion and relevanceUCLR provides excellent patient-reported and clinical outcomes to patients at medium-term follow-up with low complication and revision rates. In addition, high rates of RTP at pre-injury level and career longevity were reported by baseball players following UCLR.Level of evidenceLevel IV; Systematic Review

Background Several articles have been published reporting on the clinical performance of a novel pegged, all-polyethylene glenoid component design which features a central peg, circumferentially fluted, interference-fit peg for tissue integration and three small peripheral pegs for cementing. However, no systematic review exists to this date. Methods The US National Library of Medicine (PubMed/MEDLINE), EMBASE, and the Cochrane Database of Systematic Reviews were queried for publications up to May 2020. Results Overall, 13 articles were included for analysis (560 operated shoulders, range of mean follow-up: 2–6 years). The survival rate was 98.2% (550 out of 560 cases), while the rate of aseptic loosening was 0.2% (1 out of 560 cases). There were 139 cases (out of 399 reported; 34.1%) with peri-glenoid radiolucency, and 35 cases (out of 223 reported; 15.7%) of asymptomatic central peg osteolysis, with 1 of them undergoing revision. Conclusions There was fair quality of evidence to show that partially cemented all-polyethylene pegged bone-ingrowth glenoid components produce promising results, with a low revision rate in the short- to medium-term follow-up. Nevertheless, this analysis showed high rates of both radiolucency of the glenoid component and osteolysis around the central peg which raise concern for potential failure of this glenoid component in the long-term follow-up.

Objective: The objective of this study is to evaluate the results and complications of the subtalar arthrodesis technique conducted via arthroscopy. Methods: Searches were run on PubMed/Medline and Google Scholar for publications dated from 2007 to 2020. Original articles were included that reported the results of at least one comparative postoperative scale. Methodological quality was assessed using the PRISMA tool. Union rate, complications, and the American Orthopedic Foot and Ankle Society (AOFAS) score were prioritized. Results: A total of 124 references were identified and, after application of the inclusion and exclusion criteria and the PRISMA tool, 9 articles were eligible. A total of 180 patients were analyzed, with mean postoperative follow-up of 18 months (± 6) and with before and after AOFAS scores varying from 44 to 79 with p<0.001, demonstrating statistical relevance with significant improvement of AOFAS scores during the postoperative period. Deformity correction, improvement of pain, and rates of union were good and there was clinical improvement according to postoperative AOFAS scores, with few complications. However, the heterogeneous nature of studies, withvariations in techniques and samples, prevents generalization of the findings. Conclusion: The results of arthroscopic surgery for subtalar arthrodesis are good and rates of complications are low, but there are stillfew studies with high evidence levels that demonstrate the efficacy of the technique, although preliminary results are encouraging.

Context: There is currently no evidence-based consensus on how to treat a full-thickness, symptomatic articular cartilage injury of the patella, although numerous treatment options are available. Objective: To systematically evaluate the functional outcomes after operative treatment of patellar cartilage lesions. Our secondary purpose was to evaluate radiographic outcomes after treatment. Data Sources: PubMed, Cochrane, and Embase Study Selection: Studies published between January 1, 1990 and December 31, 2018 that included patient-reported functional outcomes for patients after operative treatment of patellar chondral defects at a minimum 2-year follow-up were included. Study Design: Systematic review. Level of Evidence: Level 4. Data Extraction: MINORS (Methodological Index for Non-Randomized Studies) score, level of evidence, sample size, demographic data, follow-up data, intervention, functional outcome scores, and magnetic resonance imaging (MRI) data were collected. Results: The review identified 10 studies and 293 patients receiving cartilage restoration procedures for patellar chondral defects with extractable clinical and radiographic results and data on complications and reoperations. All treatments (autologous chondrocyte implantation [ACI], matrix-induced ACI [MACI], autologous osteochondral transplantation [AOT]) utilized in the management of patellar chondral lesions, with the exception of isolated particulated juvenile articular cartilage, demonstrated statistically significant improvements in functional outcome scores compared with preoperative measurements at a minimum of 2-year follow-up. Postoperative MRIs were obtained in 6 studies and found that regardless of treatment, moderate-to-complete infill of patellar cartilage lesions was seen in the majority of patients. While failure rates were low for the various treatment modalities, rates of reoperation were substantial, with up to 40% to 60% reoperation rate seen after ACI. Conclusion: Patients treated with ACI, MACI, and AOT all demonstrated statistically significant improvements in functional outcome scores with radiographic evidence of healing at minimum of 2-year follow-up. Evidence is insufficient to recommend one particular treatment over another.

Background: Athletes in the Women’s National Basketball Association (WNBA) and National Basketball Association (NBA) are subject to high injury rates given the physical demands of the sport. Comprehensive data regarding injury patterns and rates in these athletes are limited. Purpose: To summarize available data on orthopaedic and sports medicine–related injuries through 2020 in professional female and male basketball players. Study Design: Systematic review; Level of evidence, 4. Methods: A search was conducted using PubMed and Embase through April 5, 2020, to identify injury studies regarding WNBA and NBA players. Studies were included if the injury or surgery was considered a direct consequence of game play including musculoskeletal/orthopaedic, concussion, ophthalmologic, and craniomaxillofacial injuries. Systematic reviews, screening studies, or studies without sufficient WNBA or NBA player subgroup analysis were excluded. Results: A total of 49 studies met inclusion criteria, 43 (87.8%) of which detailed musculoskeletal injuries. The lower extremity represented 63.3% of studies. A majority (59.2%) of studies were level 4 evidence. The source of data was primarily comprehensive online search (n = 33; 67.3%), followed by official databases (n = 11; 22.4%). Only 3 studies concerned WNBA athletes compared with 47 that concerned NBA athletes. The lowest return-to-play rates were cited for Achilles tendon repairs (61.0%-79.5%). Variability in return-to-play rates existed among studies even with similar seasons studied. Conclusion: The majority of literature available on orthopaedic and sports medicine–related injuries of NBA and WNBA athletes is on the lower extremity. The injuries that had the greatest effect on return to play and performance were Achilles tendon ruptures and knee cartilage injuries treated using microfracture. The reported outcomes are limited by heterogeneity and overlapping injury studies. There are limited available data on WNBA injuries specifically.

Objectives: While numerous studies exist evaluating the short-term clinical outcomes for patients who underwent arthroscopy for osteochondritis dissecans (OCD) of the capitellum, literature on long-term clinical outcomes for a relatively high number of this subset of patients from a single institution is limited. We performed a retrospective analysis on all patients treated surgically for OCD of the capitellum at our institution from January 2001 to August 2018. Our hypothesis was that clinical outcomes for patients treated arthroscopically for OCD of the capitellum would be favorable, with improved subjective pain scores and acceptable return to play for these patients. Methods: Inclusion criteria for this study included the diagnosis and surgical treatment of OCD of the capitellum treated arthroscopically with greater than 2-year follow-up. Exclusion criteria included any surgical treatment on the ipsilateral elbow prior to the first elbow arthroscopy for OCD at our institution, a missing operative report, and/or any portions of the arthroscopic procedure that were done open. Follow-up was achieved over the phone by a single author using three questionnaires: American Shoulder and Elbow Surgeons – Elbow (ASES-E), Andrews/Carson KJOC, and our institution-specific return-to-play questionnaire. Results: After the inclusion and exclusion criteria were applied to our surgical database, our institution identified 101 patients eligible for this study. Of these patients, 3 were then excluded for incomplete operative reports, leaving 98 patients. Of those 98 patients, 81 were successfully contacted over the phone for an 82.7% follow-up rate. The average age for this group at arthroscopy was 15.2 years old and average post-operative time at follow-up was 8.2 years. Of the 81 patients, 74 had abrasion chondroplasty of the capitellar OCD lesion (91.4%) while the other 7 had minor debridement (8.6%). Of the 74 abrasion chondroplasties, 29 of those had microfracture, (39.2% of that subgroup and 35.8% of the entire inclusion group). Of the microfracture group, 4 also had an intraarticular, iliac crest, mesenchymal stem-cell injection into the elbow (13.7% of capitellar microfractures, 5.4% of abrasion chondroplasties, and 4.9% of the inclusion group overall). Additional arthroscopic procedures included osteophyte debridement, minor synovectomies, capsular releases, manipulation under anesthesia, and plica excisions. Nine patients had subsequent revision arthroscopy (11.1% failure rate, 5 of which were at our institution and 4 of which were elsewhere). There were also 3 patients within the inclusion group that had ulnar collateral ligament reconstruction/repair (3.7%, 1 of which was done at our institution and the other 2 elsewhere). Lastly, 3 patients had shoulder operations on the ipsilateral extremity (3.7%, 1 operation done at our institution and the other 2 elsewhere). To control for confounding variables, scores for the questionnaires were assessed only for patients with no other surgeries on the operative arm following arthroscopy (66 patients). This group had an adjusted average follow-up of 7.9 years. For the ASES-E questionnaire, the difference between the average of the ASES-E function scores for the right and the left was 0.87 out of a maximum of 36. ASES-E pain was an average of 2.37 out of a max pain scale of 50 and surgical satisfaction was an average of 9.5 out of 10. The average Andrews/Carson score out of a 100 was 91.5 and the average KJOC score was 90.5 out of 100. Additionally, out of the 64 patients evaluated who played sports at the time of their arthroscopy, 3 ceased athletic participation due to limitations of the elbow. Conclusions: In conclusion, this study demonstrated an excellent return-to-play rate and comparable subjective long-term questionnaire scores with a 11.1% failure rate following arthroscopy for OCD of the capitellum. Further statistical analysis is needed for additional comparisons, including return-to-play between different sports, outcome comparisons between different surgical techniques performed during the arthroscopies, and to what degree the size of the lesion, number of loose bodies removed or other associated comorbidities can influence long-term clinical outcomes.
